CYCLE-SADDLE ATTACHMENT-BOSS.

SPECIFICATION forming part of Letters Patent N 0. 575,542, dated January 19, 1897. Application filed September 19, 1896. Serial No. 606,390. (No model.) Patented in England September 24, 1894:, No. 18,090.

To all whom it may concern:

BeitknownthatLJoHN BOULTBEE BROOKS,

manufacturer, trading as J. B. BROOKS &

COMPANY, a subject of the Queen of Great Britain, residing at Criterion Works, Great Charles Street, in the city of Birmingham, England, have invented certain new and useful Improvements in Cycle-Saddle Attachment-Bosses, of which the following is a specification, and for which I have obtained Letters Patent of Great Britain bearing date the 24th day of September, 1894, and numbered 18,090.

This invention relates to the attachmentbosses of cycle-saddles, and has for its object more efficient means of securing the saddleframing to the boss and the boss to the L-pin or seat-pillar of a machine by one operation.

Figure 1 of the accompanying drawings represents a cycle-saddle with the framing fitted with a boss made according to my invention. Fig. 2 represents an end elevation of the boss with the framing sides of the saddle in section. Fig. 3 is a vertical section of Fig. 2 upon the dotted line Fig. 4 is a side elevation of Fig. 2, and Fig. 5 is an under side plan of Fig. 2. Fig. 6 represents elevations and sections of the separated component parts of the boss. Fig. 7 shows my invention applied to single-sided Wire framings. Figs. 8 and 9 represent front and side elevations of my improved boss applied to a saddle having a pierced sheet-metal frame. Fig. 10 represents a modified form of my invention. Fig. 11 shows the component parts of the same separated.

In Figs. 1 to 6, a is a band-clip Whose free ends a are bossed and formed with eyes or holes (t wherethrough the transversely-directed pin 1), having a middle bearing-block c threaded upon it, passes, while the inner faces of the said ends a are formed with inclined planes a which impinge upon like inclined planes 0 of the pressure-block 0, whose bearin g-face c is concaved to the general contour of the L-pin or seat-pillar, and the eye 0 wherethrough the pin 5 passes, has a clearance to admit of the advancement of the block onto the L-pin or seat-pillar.

d are inner washers threaded upon the pin 19 and coming on the opposite side of the clip and with the holes (1 in the same taking over the set collars a on the outer faces of the said clip ends, while the hardened teeth or serrations d on the inner faces of the said washers are adapted to be embedded into the softer metal of the adjacent faces of the clip when the same is tightened up.

d are keep-grooves between which and opposed keep-grooves 6, made across the faces of the outer washers e, also threaded on the respective ends of the pin 1), the frame wires or rods f come and are there secured by the screwing up of nuts g on the wormed outer ends b of the said pin.

It will be observed that the keep-grooves in the opposed washers run in a direction at right angles to the teeth (Z on the inner faces of the inside washers d.

To secure the framing to the boss and the boss to the L-pin or seat-pillar, rotate one or other of the nuts 9 on the ends of the pin 5, when the free ends a of the clip are gradually closed and the inclined planes a on their inner faces are made to impinge upon the inclined planes 0 of the pressure or hearing block 0 and bring the same down bya wedge action upon the L-pin or seat-pillar embraced by the clip a, and on the tightening up of the said nuts the frame sides f are gripped between the opposed washers d and e, which are capable of rotating to admit of the universal tilting adjustment of the framing-wires of the saddle clamped between them.

hen the parts of the boss are loose, the framing-wires admit of tilt adjustment by rotating with the gripping-washers, and also of longitudinal adjustment relative to the clip by sliding between the said washers, and, further, the clip can be bodily moved along the L-pin or up and down the seat-pillar, and after the framing and parts of the boss have been adjusted to their required positions the framing is secured to the boss and the boss to the L-pin or seat-pillar by the single operation of screwing up one of the nuts g.

In Fig. 7 the outer washers 6 each have a foot 6 which takes into one of the keepgrooves of the inner washer d, and thus retain the said Washers parallel when a single frame-wire only is employed at each side.

Figs. 8 and 9 are marked with the same letters of reference as Figs. 1 to 6.

In Figs. 10 and 11 the pressure-bearing ICO block is made integral with the pin. Thus a is the clip, with the free wedge-shaped ends a impinging upon the inclined planes 0 of the pressure-block 0, formed at the middle of and integral with the cross-pin b, which passes through holes a in the free ends of the clip, whose outer faces are serrated at a and are opposed to keep-grooved washers e, and between the faces a and washers c the frame-rods f come and are clamped by the screwing up of nuts 9 on the wormed ends I) of the pin.

llaving fully described my invention, what I desire to claim and secure by Letters Patent is 1. In a cycle-saddle attachment, the combination of the band-clip it provided upon the inner adjacent faces of its free ends with inclined planes a the cross-pin b passing through said ends of the clip and provided with nuts tapped over its ends for drawing the ends of the clip toward one another, means for attaching a saddle-frame to said clip, and a pressnre-block 0 carried by said cross-pin and provided with inclined planes 0 which are engaged by the inclined planes (1 when the ends of the clip are clamped and the pressure-block thereby caused to grip the saddle-support, substantially as described.

2. In a cycle-saddle attachment, the combination of the band-clip a provided upon the inner adjacent faces of its free ends with inclined planes a the cross-pin 12 passing through said ends of the clip, apressurc-block 0 carried by said cross-pin and provided with inclined planes 0 which are engaged by the inclined planes a on the clip, Washers arranged on the opposite ends of the cross-pin and grooved on their adjacent faces for grasping the saddle-frame and nuts tapped over the threaded ends of said cross-pin outside said washers and operating when screwed up to cause said washers to grasp the saddleframe and cause the inclined planes to force the pressure-block against the saddle-support in the clip, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
